Barry (Grant Gustin) is living his dream life – his parents are alive, he’s asked Iris West (Candice Patton) on a date and he can finally be a normal guy as Central City has another speedster, Kid Flash (Keiynan Lonsdale), running around saving the city. When Barry starts forgetting parts of his old life, the Reverse Flash (guest star Matt Letscher) taunts his nemesis and tells him that there will be serious repercussions for Barry and the ones he loves if he continues to live in this alternate universe. In addition to losing his memories, his powers will also start to fade. When disaster strikes, Barry must decide if he wants to continue to live in this world as Barry Allen or return to his universe as The Flash.

Picking up with the Flashpoint-y ramifications of Barry’s season-ending timeline tampering, The Flash Season 3 features Tom Felton (Harry Potter) in the series regular role of CSI Julian Dorn, plus recurring players/guest stars Ashley Rickards (Awkward) as the head-spinning villainess The Top, Grey Damon (Friday Night Lights) as Mirror Master, Todd Lasance (Vampire Diaries) as speedster The Rival, Joey King (Fargo) as the metahuman Magenta and Susan Walters (Vampire Diaries) as Caitlin’s mother.
